Molecule-based nonlinear optical switch with highly tunable on-off temperature using a dual solid solution approach

Autor: Shi-Yong Zhang, Xia Shu, Ying Zeng, Qing-Yan Liu, Zi-Yi Du, Chun-Ting He, Wei-Xiong Zhang, Xiao-Ming Chen

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-8 (2020)

Switching of nonlinear optical signals is attractive for photoelectronics and photonics, but development is hindered by a lack of control over the switch temperature. Here the authors report a coordination polymer system that serves as an alloy-like

Approaching the activity limit of CoSe2 for oxygen evolution via Fe doping and Co vacancy

Autor: Yuhai Dou, Chun-Ting He, Lei Zhang, Huajie Yin, Mohammad Al-Mamun, Jianmin Ma, Huijun Zhao

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-9 (2020)

While electronic-structure engineering lies at the heart of catalyst design, most previous studies utilize only one technique to tune the electronic states. Here, authors demonstrate that Fe doping and Co vacancy work synergistically to approach the

Accelerating water dissociation kinetics by isolating cobalt atoms into ruthenium lattice

Autor: Junjie Mao, Chun-Ting He, Jiajing Pei, Wenxing Chen, Dongsheng He, Yiqing He, Zhongbin Zhuang, Chen Chen, Qing Peng, Dingsheng Wang, Yadong Li

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)

Water splitting provides an appealing route to generating carbon-neutral fuel, however the scarcity and cost of platinum, often used as a catalyst, necessitates a search for alternatives. Here, authors show cobalt atoms in ruthenium nanosheets to aff

Oriented electron transmission in polyoxometalate-metalloporphyrin organic framework for highly selective electroreduction of CO2

Autor: Yi-Rong Wang, Qing Huang, Chun-Ting He, Yifa Chen, Jiang Liu, Feng-Cui Shen, Ya-Qian Lan

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)

While CO2 reduction provides a way to remove carbon from the atmosphere, it is challenging to design effective, selective materials for this process. Here, authors construct metal-organic frameworks from polyoxometalates and porphryins to direct elec
